Cylinder liners are a common feature within engine blocks, and they are a sort of sleeve that lines the internal walls of a cylinder to safeguard metallic surfaces from wear and tear. As motors operate, pistons will pivot within a cylinder with rapid speed, resulting in a high pressure and temperature environment being formed. With a cast iron cylinder and an optimal liner, the service life of the assembly can be safeguarded from such stressors. In this blog, we will discuss cylinder liners in more detail, allowing you to have a better understanding of their functionality and types.
